High Depth

A novel crankshaft and camshaft measurement system by optoelectronic scanning of which a flat-crystal was used to generate high depth of parallelism scanning laser was implemented. The general structure and principle were given. Mass of test results showed that the system could achieve high precision. The ranges could achieve ±8μm, standard deviation could achieve 3μm, and easy to operate, work reliably, automatically and on line measurement could be implemented.

Measurement And Control

Based on open NC system architecture, embedded condition monitoring and diagnosis units were studied with the characteristics of modularization and reconfigurable. The intelligent measurement and control unit can be used to on-line monitoring, fault early warming, intelligent diagnosis and remote maintenance, it provied a solution for group integration monitoring system construction of high-grade NC machine. In this paper, the implementation and function of the intelligent measurement and control unit were introduced from 4 aspects including whole framework, hardware, software and XPE OS. An example of cutting force on-line monitoring were given, which operate well for alarming in unstable cutting condition.

A kind of the measurement technique of the dimension and the geometry error of large dimension workpiece with two light routes and two CCD sensors has been made. The mathematical models of the dimension and the geometry error based on the technology of CCD and laser are established. The application property parameter to measure workpiece dimension and geometry error and the design characteristic related supplemental hardware of CCD sensor are studied. An on-line data collection system based on laser and liner array CCD is developed. This systematic C8051 single-chip microcomputer as controler that adopt American CYGNAL company's production carry out handling and the collection of data. the system meets the measurement requirement of no-touch, on line and high precision with adopting of machine, laser and electricity comprehensive technology. The result can be got in this paper: the CCD sensor can meet the need of measuring dimension and geometry error of big workpiece and is no-touch, on line measurement and high precision. The on line collecting data system can achieve the expecting function, and measure data on line, and it also can easily connect with auto control apparatus.
